The Vitamin Shoppe Vitamina B2 100 mg - 300 Cápsulas

What is Vitamin B2 (Riboflavin)?

Vitamin B2, also known as riboflavin, is a water-soluble vitamin essential for energy metabolism. It acts as an enzymatic cofactor in key processes that transform food into usable energy for the body. Additionally, it participates in the maintenance of tissues such as skin and mucous membranes, and in protecting cells from oxidative damage.

This supplement from The Vitamin Shoppe provides 100 mg of riboflavin per capsule, a dose significantly higher than the recommended daily intake, designed for those seeking extra support in their daily routine.

Main benefits backed by science

According to the European Food Safety Authority (EFSA), riboflavin contributes to multiple bodily functions:

• Normal energy metabolism: Helps convert carbohydrates, fats, and proteins into energy.
• Nervous system function: Participates in nerve transmission and neurotransmitter synthesis.
• Maintenance of mucous membranes: Promotes the health of mucous membranes, including those of the digestive tract.
• Red blood cell formation: Involved in the production of erythrocytes, essential for oxygen transport.
• Iron metabolism: Facilitates the absorption and utilization of iron in the body.
• Antioxidant protection: Helps neutralize free radicals, protecting cells from oxidative stress.

These benefits make vitamin B2 a key nutrient for maintaining optimal health, especially during times of increased energy demand.

Recommended dosage and available forms

The recommended daily dose of riboflavin for adults is 1.4 mg (men) and 1.6 mg (women). However, this supplement provides 100 mg per capsule, a much higher amount used in specific contexts, such as under professional supervision or to meet elevated needs.

The riboflavin present in this product is the inactive form (riboflavin base), which is converted in the body into its active forms (FMN and FAD). Although riboflavin 5'-phosphate (active form) is available in other supplements, riboflavin base is well absorbed and effective for most people.

It is recommended to take one capsule daily with a meal for better absorption. Do not exceed the recommended daily dose.

Who should take riboflavin?

This supplement can be beneficial for:

• People with restrictive diets: Vegans, vegetarians, or those following low-dairy and low-meat diets, main sources of riboflavin.
• Athletes: Increased energy expenditure can increase the need for B vitamins.
• Over 50s: Nutrient absorption may decrease with age.
• People with certain health conditions: Such as migraines (under medical supervision) or intestinal absorption problems.

It is always advisable to consult a healthcare professional before starting any supplementation.

Possible side effects and contraindications

Riboflavin is generally safe and well-tolerated. Being a water-soluble vitamin, excess is eliminated through urine, which can cause intense yellow discoloration (harmless). In very high doses, some people may experience mild gastrointestinal discomfort.

No significant contraindications have been established, but caution is recommended in pregnant or breastfeeding women, as well as in people with liver or kidney diseases. Consult your doctor if you are taking other medications.

Food supplements should not be used as a substitute for a balanced and varied diet. Do not exceed the recommended daily dose.
